{"version":"1.0","type":"rich","title":"Fork of Activity 7 sample","description":"This fork of Activity 7 shows a horizontal bar chart of 2020 population estimates for 30 countries, with bars colored green on an SVG rendered through React. The code uses d3.scaleBand for the categorical y-axis, d3.scaleLinear for the quantitative x-axis, and d3.format to abbreviate tick labels (e.g., “B” for billions). Data is loaded from a CSV file via d3.csv and transformed by multiplying the “2020” column by 1000. Axes and marks are built declaratively as React components, with a `<title>` element providing a native tooltip on each bar.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/120c9c9dd3dd44e283500a3beb6fa0ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
